摘　　要：获得缺乏的涡轮叶片涂层表面温度分布数据是当前航空发动机材料设计面临的关键问题,数据缺乏严重限制了中国先进飞行器的性能提升。热障涂层(涡轮叶片用)添加少量稀土发光元素后可成为一种新型智能材料——智能热障涂层(STBC),是目前实现发动机服役叶片涂层温度分布测定最有潜力的方法。本文详细介绍了智能热障涂层在线(热障传感涂层)/离线(热历史涂层)测温的原理和方法。基于不同智能涂层的制备工艺,阐述了近年来利用智能热障涂层技术对航空发动机热端部件的表面温度分布及界面温度梯度检测的研究进展。基于航空发动机不同热端部件的测温需求,总结了目前国内外智能热障涂层测温技术的实际工业应用。且基于现有稀土元素掺杂对热障涂层本征性能的影响,说明了智能热障涂层实际应用的可行性。最后指出了该技术实际应用于航空发动机热端部件测温仍需解决的问题,并对其发展方向进行展望。The lack of surface temperature distribution data of turbine blade coating is a key problem in the current aero engine material design,which seriously limits the performance improvement of advanced aircraft.Thermal barrier coating(for turbine blades)doped a small quantity of rare earth elements has the potential to evolve into a novel intelli-gent material known as Smart Thermal Barrier Coating(STBC).This currently represents the most promising method for determining the temperature distribution of coated blades during engine service.In this paper,the principle and method of on-line(thermal barrier sensor coating)/off-line(thermal history coating)temperature measurement of STBC are introduced in detail.The research progress of surface temperature distribution and interface temperature gradient detection of aero-engine hot end components based on different preparation processes of STBCis also intro-duced.Based on the temperature measurement requirements of different aero-engine hot end components,the practi-cal industrial applications of STBC at home and abroad are summarized.Based on the effect of rare earth element doping on the intrinsic properties of thermal barrier coatings,the feasibility of practical application of thermal barrier coatings is demonstrated.Finally,the problems that need to be solved in the application of this temperature measure-ment technology to the thermometry of aero engine hot end components are pointed out,and its development direction is prospected.
